It's been a long, single-tasking journey but Apple finally released OS 4 for the iPhone, and one of the key upgrades includes the ability to multitask. Took you long enough, Darth Jobs! Developers and users will now have the ability to run multiple applications at once, and Apple also demonstrated the Skype app running in the background (does that mean the next-gen iPhone will have a forward-facing camera?) as well as streaming audio apps like Pandora and Last.fm. Apple also unveiled folders for the iPhone that makes it easy to organize all your apps into customizable categories.

Unfortunately, not all of our prayers were answered in this latest update. The iPhone still can't go into mass storage mode, it can't tether to a computer, no Flash support or FM radio, and of course, the biggest issue is that it's still exclusively on the unreliable AT&T network. Wilson was hoping for Wi-Fi syncing but apparently Apple makes too much money on selling iPhone cables to worry about wireless.

Big thanks to everyone for pointing us to CheckFacebook.com that answers yesterday's question about the percentage of Americans on the site. Unsurprisingly, the U.S. has the highest number of FB users at 94,748,820, with the U.K. at a not-so-close second. Also be sure to listen carefully during E-Mails From the Public to learn how to say "Facebook" in Chinese!
